Danza de los Diablitos (The Dance of the Little Devils) is a three-day annual festival, held December 31 through January 2 by the Boruca people, an indigenous people in Costa Rica. The male participants of the tribe perform a ritual dance re-enacting the Spanish conquest wearing elaborate costumes. The most important part of the costumes are the masks. With the mask, each member is empowered to fight and dispel the evil of the Spanish invaders who are represented by a mock bull. The festival masks use demon features which the indigenous people adopted symbolically from the Spanish Catholics.
